Doctor delivers 4 sets of twins in 24 hours

He's been an obstetrician-gynecologist at Gundersen Lutheran Medical Center for 19 years, but he said he's never experienced a 24-hour on-call period like the one he put in on Friday and Saturday, when he delivered four sets of twins.

&quot;I don't think I ever delivered two sets of twins on a call day,&quot; Merkitch said.

&quot;It was hard to believe that everything was coming in twos, but after a while you're up all night, you might as well keep delivering babies,&quot; he said.

&quot;It's something I don't think I'll see again.&quot;

Merkitch delivered one other baby during his shift; he also couldn't recall ever delivering nine babies during a similar shift.
